The batcher needs to observe two different channel timeouts.
1. the consensus channel timeout, so it knows when to resubmit a channel
   whose frames didn't land on L1 quickly enough and
2. the channel submission timeout, by which time it closes the channel
   even if the target amount of data hasn't been put into the channel
   yet.

feat(mon): set up chain-mon package

This commit gets the foundry tests up to parity for the
`AssetReceiver` and `Transactor` and then deletes the
hardhat tests. Now this package only has foundry based
tests which makes it much easier to standardize longer
term with a single way of developing smart contracts
in the monorepo.
